Coasts of Admiralty Gulf except in the vicinity of Osborne Islands; east to Monger Creek in Napier Broome Bay; south only to southern rim of valley of King Edward River; a horde on Sir Graham Moore Island, whose people were chiefly marine food gatherers (Tindale 1974).(On McGregor's map 1983, it extends further to East.)

The general association was to the coast from the Osborne Islands to Poempangala Hill, and attendant drainages into this section of coast. In his description of Wunambal, Tindale states 'the Tjawurungari (Tawandjangango) were on the Osborne Islands. The last-named were also called Wilawila people and their language is thought to have affinities with Kambure. According to a native informant they are 'light Kambure' speakers. Another tribe claiming the name Wilawila lives on the Carson River (see separate heading)'. The motivation for Tindale excluding the Osborne Islands from the Gaambera area is obscure, especially as his informant described them as speaking Gaambera. In 2007, nobody recognized the name Wila-Wila as applying to the Carson River area. However, two separate sources recognized the name as applying focally to an insular Wunambalic variety. One source specifically associated the name to Bigge Island and the adjacent coastal Hunter River area. This is within Wunambal country.Tom Vigilante stated that his understanding was that the area was Gaambera. Vigilante also stated that the drainage of Monger Creek was Gaambera, with the eastern boundary being in the Poempangala hill range. Anthony Redmond stated that the name Gaambera did not extend into the King Edward River drainage (Harvey AILEC 0802).

Wunambal Gaambera Country lies in the north west Kimberley area of Western Australia. It incorporates some 200 kilometers of coastal and inland country, from Prince Frederick Harbour in the south west to Napier Broome Bay in the northeast, including parts of the King Edward River, the Anjo and Bougainville Peninsulas, the Mitchell and Gardner Plateaus, the Mitchell and lower Roe Rivers, the Bonaparte Archipelago and the Admiralty Gulf Aboriginal Reserve. It also includes large areas of intensely dissected coastal country, the seas of the Bonaparte Archipelago and Admiralty Gulf with many islands, the largest being Bigge Island, estuaries bays and harbours' (Karadada et al. 2011:10)

Contemporary location Wunambal Gaambera people mainly live in the communities of Kalumburu, Kandiwal and Mowanjum near Derby, with some speakers also living in Kununurra and Wyndham, as well as a few outstations and camps in the dry season. (Karadada et al. 2001:10).
